An Examination of the Influence of Band Director Teaching Style and Personality on Ratings at Concert and Marching Band Events

This descriptive correlational study examined the relationship between high school band directors\u27 teaching style and personality and their ratings in marching and concert band festivals using the Five-Factor Model of personality and Gumm\u27s Music Teaching Style Inventory. The sample (N=176) consisted of 46% of all high school band directors in Florida. Criterion variables included marching and concert festival ratings, state concert band ratings, Florida Marching Band Coalition marching competition scores, frequency of attendance of these last two events, and the balance between marching and concert band. Predictor variables included thirty personality facets and eight teaching styles. Four demographic variables included gender, experience, academic degree, and primary instrument. One predictor, Time Efficiency, stood out as having particularly strong correlations with all of criterion variables. Regression models produced the following findings: 23% of the variation in concert band ratings can be explained from Time Efficiency, Immoderation, Music Concept Learning Assertiveness, and Nonverbal Motivation; 22% of the variation in marching band scores can be explained by Time Efficiency, Music Concept Learning, Imagination, Modesty, Cheerfulness, and Anxiety; 20% of the variation in participation in state Florida Bandmasters Association concert band festival participation can be explained by Time Efficiency, Positive Learning Environment, Immoderation, Music Concept Learning, Group Dynamic, and Assertive Teaching, and 11% of the variation in FMBC competitive marching band event attendance can be explained by Time Efficiency, Nonverbal Motivation, Dutifulness, and Modesty. Most subjects (84.3%) were balanced, while the remaining 15.7% were marching oriented. There was no significant difference in marching ratings between groups, although balanced subjects scored significantly higher in concert band and attended significantly fewer marching competitions. A discriminant function selected four predictor variables with a significant effect: Assertiveness, Immoderation, Adventurousness, and Emotion (Wilks\u27 λ = .84, χ2 = 23.42, df = 4, p less than .001) which was able to successfully predict group membership 72.3% of the time. Recommendations include emphasizing the concert band as the core and playing concert music all year. Directors may benefit from being cognizant of their personalities and teaching styles which may enable them to modify their behavior and practices when appropriate to be more effective teachers

Exact beta function from the holographic loop equation of large-N QCD_4

We construct and study a previously defined quantum holographic effective action whose critical equation implies the holographic loop equation of large-N QCD_4 for planar self-avoiding loops in a certain regularization scheme. We extract from the effective action the exact beta function in the given scheme. For the Wilsonean coupling constant the beta function is exacly one loop and the first coefficient agrees with its value in perturbation theory. For the canonical coupling constant the exact beta function has a NSVZ form and the first two coefficients agree with their value in perturbation theory.Comment: 42 pages, latex. The exponent of the Vandermonde determinant in the quantum effective action has been changed, because it has been employed a holomorphic rather than a hermitean resolution of identity in the functional integral. Beta function unchanged. New explanations and references added, typos correcte

Chiral symmetry in the 2-flavour lattice Schwinger model

We study the 2-flavour lattice Schwinger model: QED in D=2 with two fermion species of identical mass. In the simulation we are using Wilson fermions where chiral symmetry is explicitly broken. Since there is no known simple order parameter it is non-trivial to identify the critical line of the chiral phase transition. We therefore need to find observables which allow an identification of a possible restoration of chiral symmetry. We utilize the PCAC-relations in order to identify the critical coupling, where chiral symmetry is restored.Comment: 3 pages (LaTeX), 4 figures (EPS

Signal at subleading order in lattice HQET

We discuss the correlators in lattice HQET that are needed to go beyond the static theory. Based on our implementation in the Schr\"odinger functional we focus on their signal-to-noise ratios and check that a reasonable statistical precision can be reached in quantities like $f_{B_s}$ and $M_{B^\star}-M_B$.Comment: 3 pages, Lattice2004(heavy), v2: corrected definition of X^{kin/spin

A Lemaitre-Tolman-Bondi cosmological wormhole

We present a new analytical solution of the Einstein field equations describing a wormhole shell of zero thickness joining two Lema{\i}tre-Tolman-Bondi universes, with no radial accretion. The material on the shell satisfies the energy conditions and, at late times, the shell becomes comoving with the dust-dominated cosmic substratum.Comment: 5 pages, latex, no figures, to appear in Phys.

Heavy-light baryonic mass splittings from the lattice

We present lattice estimates of the mass of the heavy-light baryons $\Lambda_b$ and $\Xi_b$ obtained using propagating heavy quarks. For $\Lambda_b$ our result is $M_{\Lambda_b}=5.728 \pm 0.144 \pm 0.018$ GeV, after extrapolation to the continuum limit and in the quenched approximation.Comment: 3 pages postscript, Contribution to Lattice'9

Root Morphology, Allometric Relations and Rhizosheath of Ancient and Modern Tetraploid Wheats (Triticum durum Desf.) in Response to Inoculation with Trichoderma harzianum T-22

Early root traits and allometrics of wheat are important for competition and use of resources. They are under-utilized in research and un-explored in many ancient wheats. This is especially true for the rhizosheath emerging from root-soil interactions. We investigated root morphology, root/shoot relations and the amount of rhizosheath of four tetrapoid wheat seedlings (30 days after emergence): the italian landrace Saragolle Lucana and modern varieties Creso, Simeto and Ciclope, and tested the hypothesis that inoculation with Trichoderma harzianum T-22 (T-22) enhances rhizosheath formation and affects wheat varieties differently. Overall growth of non-inoculated plants showed different patterns in wheat varieties, with Saragolle and Ciclope at the two extremes: Saragolle invests in shoot rather than root mass, and in the occupation of space with highest (p < 0.05) shoot height to the uppermost internode (5.02 cm) and length-to-mass shoot (97.8 cm g−1) and root (more than 140 m g−1) ratios. This may be interpreted as maximizing competition for light but also as a compensation for low shoot efficiency due to the lowest (p < 0.05) recorded values of optically-measured chlorophyll content index (22.8). Ciclope invests in biomass with highest shoot (0.06 g) and root (0.04 g) mass and a thicker root system (average diameter 0.34 mm vs. 0.29 in Saragolle) as well as a highest root/shoot ratio (0.95 g g−1 vs. 0.54 in Saragolle). Rhizosheath mass ranged between 22.14 times that of shoot mass in Ciclope and 43.40 in Saragolle (different for p < 0.05). Inoculation with Trichoderma increased the amount of rhizosheath from 9.4% in Ciclope to 36.1% in Simeto and modified root architecture in this variety more than in others. Ours are the first data on roots and seedling shoot traits of Saragolle Lucana and of Trichoderma inoculation effects on rhizosheath. This opens to new unreported interpretations of effects of Trichoderma inoculation on improving plant growth
